Common Questions:

What comes in the box with the Mio Fuse?

In the box, you will receive the Mio FUSE heart rate monitoring wristband, a USB charging dock with magnetic alignment, the Mio FUSE Quick Start Guide, and Mio FUSE Warranty Information.

What colors does the Mio Fuse come in?

The Mio Fuse comes in a Black band with Aqua inside (that’s the small version) or a Black band with Crimson inside (which is the large version).

What mobile devices is the Mio Fuse compatible with?

iOS and Android devices. Not Windows.

What 3rd party apps does the Mio Fuse work with?

Some compatible 3rd party apps include Nike +, Strava, Wahoo, MapMyRun, MapMyRide, Endomondo, Runtastic, and Digifit.

Is the Mio Fuse water proof or safe for swimming?

It is waterproof to 3 meters. That means you could swim with it in a pool, just don’t go down deep.

Does the Mio Fuse have its own app?

Yes, the Mio Go app. This app is perhaps not as good as some other apps and most reviewers say that you are better off using the great 3rd party apps that the Fuse is compatible with. The Mio Go app does have some nice heart rate monitoring stats.

Does the Mio Fuse come with a warranty?

Yes, it comes with a one year limited warranty. You also get a booklet with warranty information in the box.

What Others Are Saying:

Jill Duffy, PC Mag:  “With an optical heart rate monitor for training and a stellar price, the Mio Fuse is an excellent activity tracker that’s ideal for runners and cyclists. It doesn’t track sleep or take your resting heart rate, but for active types, it’s aces and an Editors’ Choice.”

Paul Lamkin, Wareable:  “The Mio Fuse is a decent wearable, with accurate heart rate monitoring, an easy to use app and a comfortable, if somewhat slightly oversized, design. If you look at it as simply a bpm based device with some activity extras thrown in, it does the job, although the omission of basic sleep monitoring, notifications and silent alarms are a bit baffling. At (around) £130 / $149 it’s going head-to-head with the more feature packed, and complete, Fitbit Charge HR though – so it’s quite hard to fully recommend it.”

Peter Dreyer, Techradar:  “An excellent product for hardcore runners who don’t mind its cost and aesthetic failings, not a step counter for your mum.”


The Mio Fuse seems to be sort of the flagship fitness tracker from Mio, an optical heart rate tracking company, or at least it is the most popular. Given the companies known specialization in heart rate tracking, it’s no surprise that the Fuse has an excellent built in optical heart rate monitor. The Mio Go app also is setup to sort of feature the heart rate stats and does a good job of displaying heart rate based stats. I also like the 7 day battery life.

Beyond the heart rate tracking and battery life, the Mio Fuse is a bit underwhelming. It has some standard fitness tracking features like the ability to track steps, distance, calories, pace, and time. However, it is missing a sleep monitor, which is something most fitness trackers in this price range have. It also doesn’t have much for smart phone features, although there is sync to phone GPS. The Mio Go app isn’t all that great apart from the heart rate stats. That problem is kind of a non-issue as the Mio Fuse does work with 3rd party apps including Nike +, Strava, Wahoo, MapMyRun, MapMyRide, Endomondo, Runtastic, and Digifit. I’m not a fan of the huge, bulky wristband design, although it really isn’t that uncomfortable to wear. It does at least stay on your wrist and the heart rate monitor is accurate. I really dislike that the band only comes in two sizes and each size has only one color (aqua for small, red for large).

While there really isn’t anything particularly wrong with the Mio Fuse, and it works fairly well for what it does, it can’t really be denied that other devices do more for the same price or less. If your primary concern is heart rate monitoring, this might be a good device for you as the heart rate monitoring is excellent and the Mio Go app gives good stats on your heart rate tracking. The Mio optical heart rate sensors are also used in the TomTom fitness trackers, so you might want to check those out. For everyone else, I think you’d be better off with the FitBit Charge HR as it is similarly priced and has more features.
